Application filed une 21, 1917. Serial No. 176,067.

To all whom it may concern:

Be it known that I, ANTONINE ULA- NYTZKY, a subject of the Emperor of Aus tria, residing.- at Cohoes', in the county of Albany and State of New York, have invented certain new and useful Improvements in TorpedoGuards and Catchers, of WlllCll the following is a specification.

This invention relates to torpedo guards being raised to the deck of the vessel by the catching means when it is caught.

A third important object is the provision of the improved arrangement of guard which will check the speed of an approaching torpedo gradually so that upon its arrival at the electromagnetic means it will be seized magnetically withoutshock and consequent danger of explosion.

A fourth important object of the invention is the provision of an improved device of this character wherein the approaching torpedo will, in the act of being caught, close an electric circuit which will automatically operate the mechanism to raise the torpedo on to the deck of the vessel.

With the above and other objects in view, as will be hereinafter apparent the inventionconsists in general of certain noveldetails of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawing, like characters of reference indicate like parts in the several views, and

Figure'lis a transverse section through a portion of the hull of the vessel showing the apparatus in elevation.

Fig. 2 is a side elevation of a portion of the hull of the vessel with the apparatus in position. 7

Fig. 3 is a detail section 11 the line 3'3 of- Fig. 1. I p p 7 Fig. 4 is an enlarged detail view partly in section and partly diagrammatic showing the arrangement of the circuit closer and electromagnet used herewith. V

In the embodiment of the invention illus trated in the accompanying drawingsthere is seen a portion; of theliullof a vessel indicated in general at S. Mounted on this hull beneath the waterline are brackets l0 and to each of these brackets is pivoted a curved outrigger 11 provided at its free extremity with a link 12 to which is connected one end of a hoisting cable 13. This hoisting cable is led upward and inboard over a pulley over sheave 14 mounted on the davit 15. The remaining end of the cable 13 'is connected to the winding drum of a motor typically indicated at 16 Mounted on the side of the hull above each of the brackets 10 is a second bracket 17 andeach of the bracketsl? carries a sheave l8 and depending from the extremity of the davit is a sheave 19, the sheaves .18 and 19 being connected by endless ropes 20. The sheave 19 is fixed on its shaft or axle and this shaft or axle furthermore carries a pulley 21. which is connected by an endless rope or cable 22 with a pulley 23 at the base of the respective davit, the pulley 23 being provided with a handled crank 24 for the purpose of operating it. Connected to each of the cables 20 is a link 25 and-carried by the links 25 and 12 is a torpedo net 26 which is sufliciently slack when in torpedo catching position to take the curved form shown in Fig. 1, the curve being of course substantially a catenary. Just above the Water line behind each of the nets 26,which it will be observed each preferably forms a separate section, is an electromagnet having a core 27 and a winding 28 which is en'- ergized, when the device is in use, from any suitable source of power, the latter not beingdeemed necessary here to be shown. The core 27 carries on its outer end an elongated pole piece 29 the shape of which can best be seen by reference to Fig. 2. Passing through each of these pole pieces is a yoke 30 carrying on its inner end an insulated contact member 31 and having its arms connected exteriorly ofthe pole piece 29 by a bar 32. The Contact 31 is so arranged that when the yoke is moved inward itwill engage a second contact 33 as can be seen by reference to Fig.4. The contact 31 is connected by a wire 34' with a suitable source of electric energy here typically indicated by the battery 35. This battery is connected in multiple by wires respective net section. Moreover, the contact 33 is connected by wires 37 withthe remaining brushes of the motors 16 so that when, the contacts 31' and 33 close current V will flw from'the battery" 35 through the thatwhen the contact 1s closed the alarm v pedo will motors and actuate these motors to draw up upon the cables 13. Moreover, if it be desired, an alarm hell 'or other suitable alarm-as indicated at 38 may be interposed in a Suitable place'in the electric clrcuit sowill indicate such closing.

In order to understand pedo' 39 the curve of the net being, bythis action,

slowed down in speed so'that as the end of the torpedo rises out of the wateritsmo mentum will have been practically checked.

"Owing to the torped'o forcing the net in.-= 1 ward-in its movement toward the ship the net will strike the bar 32 and close the circuit above-noted.

magnet, which is constantly energized'when in-its from sliding back off of the net. Now whenthe circuit s closed and the motor 16 oper-" thedevice is, in use, will hold the torpedo raised position so that it is prevented ated the Outriggers ll'will be tricedup as ships deck.

connected to indicated in dotted lines'in Fig: 1. Thenthe crank 24 may be operated inner'edge of the net upward abovethe Suitable 1 tackle may" then be rolled out of the net onto the ships deck without danger 'to the ship or injury to the torpedo. r r

' Thus the torpedo is not only stopped from injuringtheship but is caught for future use against the enemy.

. There has thus been provided .a simple and eflicient device of the kind described and for the purpose specified.

It is obvious that many ,mmor changes may be made in the form and construction of the invention without departing from the material principles thereof. Itisnot therefore desired to confine the invention to" 'the exact form herein shown-and described 7 but it is wished to include all such as properlycome within thescope claimed. 7

Having thus described the invention, what is claimed as new, 1s:-
